Surface roughness parameters

2007-07-12 Thread María Susana Conconi
Dear all I am trying to use microabsorption corrections in Fullprof. I have Pitscheke ?s papers to understand the model but I would like to know, in practice, if there are limits to the numerical values of Po, C and tau. Is it convenient to set constrains to this values? María Susana Conconi
